Ok, not to sound like a punk, but I thought my test form was easier than the majority of my medical school exams. That might be because I only cram for most of my medical school exams at the last second. 😀
I felt like I missed anywhere from 5 to 15 questions on any section and up to 20 questions on section 3 (which ferociously abused me before my lunch). I am fairly confident I scored b/t 70-85% right overall (I'd estimate 80%). I have been looking up a lot of my questions that were marked and I seem to be doing OK, which covers me for dumb mistakes.
I think the way you "feel" after this exam depends a lot on what you expected to get. In my case, I wanted to pass (and hopefully get a 200-210+ to be more specific). I don't really want to do anything hyperspecialized beyond surgery or emergency med.
I really just wanted to walk out of that exam and still have the hope that I could still be a doctor someday... and I do. I think reading about the hyperoverachieving gunners on this site really made me uncomfortable and I think reading sdn makes us forget that passing this test only takes a cumulative percentage of 55-65% (quoting this year's kaplan qbook).
Don't forget that for every dumb mistake, comes a shot in the dark that is actually right. It'll even out.

And to review
I was freaking out before the test due to my horrific NBME 3 = 186 (2 weeks ago). This was pre-rote memorization phase.
USMLE World (55% complete) = 48% cumulative -> though it was closer to 55-60% over the past 8 days (with a peak of 64 and 70%). Kaplan - ~400 questions - (60-70%). I felt like I studied a lot but I was going no where so I just started reviewing 1st aid like crazy during the last week.
Books - First Aid x 2 (+ flashcards of 1st aid pharm, HY facts in back + path), HY Neuro, Kaplan - biochem, behavioral, and micro, Goljan's path, 1/4 of BRS path, and BRS physiology.
BTW USMLEWorld should be sued for copyright infringiement. I wish I had finished 100% of their questions just to get a couple more verbatim questions correct.
